Abstract ：
Ultrahigh-resolution polymer materials with good thermal stability and high interface contrast have a wide range of application prospects in photolithography and nanomanufacturing processes. Here, we report a series of comb-like homopolymers based on polystyrene sulfonate imidazolium salts (PSSM-(i)imi), achieving efficient self-assembly under solvent-free conditions and obtaining sub-3 nm hexagonally packed cylinders and sub-4 nm lamellar nanopatterns with high interface contrast. The sulfonic acid groups in the main chain of the homopolymers are connected to imidazole groups containing hydrophobic alkyl side chains through acid-base mixed electrostatic interactions. The electrostatic interactions enhance the incompatibility between the two functional groups, while the alkyl side chain can precisely control the domain spacing and nanostructure of the pattern, regardless of their molecular weight. Through the effect of temperature fields, the thermal stability and spatial orientation of the homopolymer nanostructures were further studied, promoting the practical application of nanopatterned materials.

Abstract ：
Oil/water separation of emulsion stands as one of the most arduous and challenging aspects in oily wastewater treatment which represents a perennial trouble for humanity. Herein, positively charged hydrophobic polymer foams (PCHPFs) were fabricated by water-in-oil (W/O) high internal phase emulsion (HIPE) polymerization followed by quaternization, employing 4-vinylbenzyl chloride (VBC) and 4-tert-butylstyrene (tBS) as the comonomers. The quaternization degree of PCHPFs which can be adjusted by varying the VBC/tBS ratio has an important influence on the emulsion separation performance based on the charge demulsification mechanism. The porous morphologies of PCHPFs were revealed by SEM. The successful fabrication of PCHPFs was confirmed by FTIR and XPS. As VBC/tBS ratio increased from 0.5:1-5:1, the emulsion separation efficiency of PCHPFs first increased to a maximum of 95.9 % at 2:1 and then decreased. Additionally, the PCHPFs demonstrated robust hydrophobicity (water contact angles > 143 degrees), exceptional oil-water selectivity, remarkable oil-water separation capability, coupled with a certain absorption capacity for various oils and organic solvents (5-14 g/g). Given these advantages, PCHPFs are anticipated to emerge as an ideal solution for emulsion separation. Most importantly, the methodology for generating PCHPFs via quaternization in this research offers an innovative avenue in the design of charge demulsification materials.

Abstract ：
The development of modern electronic devices necessitates the creation of materials that exhibit both excellent thermal conductivity and high electromagnetic wave absorption performance. This study focuses on the synthesis of a dual-functional composite material, Co-C@PDA@BN, by incorporating boron nitride (BN) onto a metal-organic framework (MOF)-derived Co-C core through the strong adhesion properties of polydopamine (PDA). The heterogeneous structural interface enhances interfacial polarization, thereby optimizing wave absorption. The thermal conductivity can be improved by adjusting the ratio of Co-C to BN. A composite with a Co-C to BN ratio of 1 : 5 shows a minimum reflection loss of -55.3 dB at 5 wt% and a thermal conductivity of 0.396 W m-1 K-1, while a ratio of 1 : 20 achieves a thermal conductivity value of 0.464 W m-1 K-1 with a minimum reflection loss of -44.9 dB, demonstrating the facile tunability of these two properties. This work provides a promising pathway via heterostructure design to balance thermal conductivity and wave absorption characteristics, which may offer guidance for advancing electronic device technology.

Abstract ：
Diffusion dialysis (DD) presents a highly promising and cost-efficient approach for acid recovery, yet its performance is often hindered by the acid permeability of anion exchange membranes (AEMs). To address this challenge, a one-step approach has been developed to fabricate porous AEMs. Using brominated polyphenylene oxide (BPPO) as the porous base membrane, imidazole is employed for in-situ crosslinking and cationization. This approach not only retains the inherent porosity (>63.5 %) of the base membrane but also achieves an exceptionally thin selective layer (<0.3 mu m), thereby creating abundant free space volume. Through a concurrent enhancement of ion transport sites and crosslinking density, the membrane effectively breaks acid permeability-selectivity trade-off. The optimal IPPO-20h AEM demonstrates a remarkable increase in both the acid dialysis coefficient (U-H+ = 34.1 x 10(-3) m/h) and separation factor (S-H+/(Fe)2+ = 573.8) in the HCl/FeCl2 system, with enhancements of 4- and 31-fold, respectively, compared to the commercial DF120 AEM, at 25 degrees C. This high-performance AEM, synthesized via a straightforward and mild process, offers significant potential for large-scale acid recovery applications.

Abstract ：
Herein, we present the synthesis and characterization of a novel phosphorus-containing epoxy co-curing agent, ANVD, fabricated via a one-pot method utilizing vanillin, 1,5-diaminonaphthalene, and DOPO as raw materials. Structural analysis conducted through FTIR and NMR spectroscopy confirmed the composition of ANVD. Differential scanning calorimetry (DSC) results indicated ANVD has significant contribution to the curing crosslinking of DGEBA, resulting in a slightly decreased Tg value for EP/ANVD compared to EP/DOPO, albeit still notably higher. Thermogravimetric analysis (TGA) revealed a reduction in the T5% and Tmax values of EP/ANVD, yet ANVD's superior char-forming ability increased char residue mass at elevated temperatures. Combustion tests showcased the outstanding flame retardancy of EP/ANVD, with EP/ANVD-5 exhibiting a limiting oxygen index (LOI) value of 33.2 % and achieving a V-0 rating in the UL-94 test. Furthermore, EP/ANVD-5 displayed a notable decrease of 38.6 % and 32.1 % in pHRR and av-HRR, respectively, compared to pure EP, surpassing EP/DOPO with equivalent phosphorus content. Analysis of decomposition products in both condensed and gas phases revealed ANVD's role in forming dense and continuous expanded char layers during combustion, releasing phosphorus radicals and non-combustible gases, thus exhibiting dual-phase flame retardant effects. Additionally, EP/ANVD-3 exhibited enhanced mechanical properties, with tensile strength and modulus increasing from 68.5 MPa and 0.75 GPa to 76.5 MPa and 0.86 GPa, respectively, compared to pure EP. Overall, the introduction of the bio-based flame retardant ANVD presents promising opportunities for the utilization of bio-based materials in flame retardancy applications.

Abstract ：
Dispersion of SiO2 particles in aqueous solutions using block copolymers remains challenging, particularly due to degradation in highly alkaline environments and difficulty in achieving high solid content. Herein, we report the synthesis of an anionic block copolymer, poly(glyceryl methacrylate-b-sodium p-styrenesulfonate) (PGGMA-b-PSSS), containing abundant hydroxyl groups, via reversible addition-fragmentation chain transfer (RAFT) polymerization of sodium p-styrenesulfonate and glycidyl methacrylate monomers. The hydroxyl groups in PGGMA-b-PSSS serve as anchoring points, producing a steric hindrance effect between SiO2 particles by interacting with silanol groups on the particle surface. Furthermore, electrostatic repulsion from the poly(sodium p-styrenesulfonate) block significantly enhances the dispersibility of PGGMA-b-PSSS in aqueous systems. A systematic investigation of the dispersibility of SiO2 particles was conducted under various compositions and concentrations of PGGMA-b-PSSS across a wide alkaline pH range. Our results show the effective dispersion of sub-micron and micron-sized SiO2 particles, achieving solid contents of up to 35 wt% over a wide pH range (3–13). © 2025 Elsevier B.V.

Abstract ：
This work reports the synthesis of CO2/ultraviolet (UV) light dual-responsive CABC-type asymmetric tetrablock polymers (CABC-ATP) based on organocatalyzed reversible complexation-mediated radical polymerization (RCMP) with methyl methacrylate (MMA), 2-Propenoic acid, 2-methyl-4-methyl-2-oxo-2H-1-benzopyran-7-yl ester (CMMA), and 2-(dimethylamino)ethyl methacrylate (DMAEMA) as block monomers by three steps. The obtained CABC-ATP has controllable number average molecular weight (Mn) and narrow molecular weight distribution (Mw/Mn = 1.18-1.29). The hydrodynamic diameter and fluorescence intensity were measured using dynamic light scattering coupled with fluorescence assays. Notably, the vesicle volume increased from an initial measurement of 247.6 nm to 285.4 nm post-experiment. The initial fluorescence emission intensity recorded was 4971, which decreased to 1412 following the introduction of carbon dioxide for 20 min. Subsequently, the fluorescence intensity recovered to 5199 upon nitrogen exposure. The response behavior of CABC-ATP to UV light is due to the cross-linking of coumarin-based monomer, resulting in the change of fluorescence intensity at the macro level. Besides, the protonation of tertiary amine is promoted by the stimulation of CO2, generating of the change of vesicle volume at the micro level.

Abstract ：
Excessive electric field strength causes the droplets to contact but not coalesce, severely deteriorating the oil-water separation efficiency. The investigation of the non-coalescence of nonidentical droplets in oil under a DC electric field is conducted using high-speed photography. The effects of droplet volume ratio and interfacial tension ratio on the characteristics and critical parameters for droplet non-coalescence are systematically explored. The results show the critical electrocapillary number for the non-coalescence of nonidentical droplets and critical contact cone angle decreases as the volume sum increases or the interfacial tension ratio decreases, which is related to the competition between the resultant electric field force and the interfacial tension force. These results contribute to optimizing the operating parameters of the electric coalescer and improving the oil-water separation efficiency.

Abstract ：
Copper metal is essential to our production process, but it is highly corrosive in an ammonia environment and must be highly valued. Anti-corrosion coating is a simple and cost-effective method of preventing metal corrosion. In this study, a composite silane coating was prepared on copper using an impregnation method with mercaptopropyltriethoxysilane (TPTES) as the silane substrate and graphene oxide (GO) modified with isophorone diisocyanate (IPDI) or isocyanatopropyltriethoxysilane (IPTS) as filler to protect the copper from ammonia corrosion. The coating samples were hanging tested against ammonia corrosion by setting up two corrosive environments: ammonia gas and ammonia water. After 20 days of corrosion, the surfaces of the TPTES/ IPDI-GO and TPTES/IPTS-GO coatings remained unchanged under both ammonia environments and the corrosion rate was consistently low at 2-3 mu m/y. Additionally, the coating exhibited high protective qualities according to the electrochemical impedance spectroscopy (EIS) test in a 3.5% NaCl solution, which is attributed to the good dispersion that improves the densification and regularity of the coating. Meanwhile, IPTS-GO has a greater binding force with the coating matrix due to the increased number of reactive sites, resulting in further improved corrosion protection. This study provides an idea for research on ammonia-resistant coatings.

Abstract ：
Composite material g-C3N4/WO3•H2O (CNW-1) was synthesized by hydrothermal reaction from graphite phase carbon nitride (g-C3N4) and sodium tungstate dihydrate. The composite material obtained was then characterized by XRD, XPS, SEM and TEM, and its visible light catalytic CO2 reduction performance at 298 K and 0.1 MPa was evaluated, the possible reaction mechanism was proposed. It was found that the yield of CO and CH4 could be regulated by adjusting the crystal water content in tungsten trioxide. CNW-1 had the highest yield of CH4 (0.33 μmol/g), while g-C3N4/WO3 (CNW) had the highest CO yield (0.67 μmol/g) after 10 h of reaction. This study provides an effective strategy for the selective reduction of CO2 to C1 compounds, and highlights the potential application of Z-scheme photocatalytic systems constructed from g-C3N4 semiconductor in the field of catalysis. © 2024 Fine Chemicals.
